Abstract: 698,160. Liquid-electrode apparatus. SOLVAY ET CIE. Nov. 7, 1951 [Nov. 7, 1950], No. 26053/51. Class 41. A cell for the electrolysis of brine comprises a sloping base 1, Fig. 1, along which a layer of mercury flows from inlet 8 to outlet 9 beneath a series of graphite anodes 5 ; when the anodecathode distance has increased to a prescribed degree due to wear of the anodes the right-hand anode is removed and replaced by its left-hand neighbour, other anodes similarly being moved one place to the right and the anode at the extreme left of the apparatus being replaced by a new anode, the points of suspension of the anodes being such that in the new arrangement the anode-cathode distances are appropriate for a further stage of operation. As shown the anodes are suspended from cover blocks 6 resting on the side walls of the cell. In the modification shown in Fig. 4 the cover walls also rest on the side walls which, however, are of stepped formation ; the spaces between successive cover plates are closed by a jointing composition not shown. In both the above arrangements, electrolyte enters at 10 and leaves at 11 ; gas exits are provided at 12, 13. In further modifications, the upper edges of the side walls are parallel to the base 1 and the anode supporting cover blocks rest on continuous or stepped angle-iron supports mounted inside the side walls. In order to take account of differences in anode. wear along the length of the cell due to varying electrolyte conductivity &c., the points of suspension of the anodes instead of lying in a horizontal plane as in the forms shown may lie on a curved surface. This surface may in some cases be higher above the cathode surface at the right hand, i.e. at the upper end of the base 1, the direction of transference of the anodes between stages in the operation previously described then being from right to left. In some cases the direction of flow of electrolyte through the cell may be contrary to that of the liquid cathode. During removal of each of the electrodes, a gas barrier is inserted to prevent influx of air to the rest of the cell and the cell is connected to an alternative gas main during these operations. Specification 602,436 is referred to.

Abstract: 1,244,503. Magnetic recording media. BURROUGHS CORP. 27 March, 1969[4June, 1968], No. 26412/68. Addition to 1,214,681. Heading H1H. [Also in Division C7] A ferromagnetic coating (e.g. of Co-P or Co-Ni-P) is deposited solely by electrolysis on an electrically conductive carrier by immersing the carrier as cathode in an aqueous electrolyte comprising cobaltous ions in the range of 10 to 80 g./1. and a source of phosphorus which comprises up to 6 g./l. of hypophosphite ions all in the absence of complexing ions in a quantity of sufficient magnitude to cause chemical deposition, maintaining the pH of the electrolyte at 3À2 to 5À0 and applying to the cathode a current density of 10 to 120 amps/ sq. ft. so as to co-deposit P and Co on the conductive carrier. The Co may be derived from CoSO 4  and the hypophosphite from H 3 PO 2  or its Na, K, Ca or NH 4  salt. The pH may be maintained by adding H 2 SO 4 . Nickel may be added to the bath as NiSO 4  and the bath may also contain added sulphate to improve electrical conductivity, H 3 BO 3  as a pH buffer and formate as a brightener. The anode may be an alloy of 80% Co, 20% Ni or may be pure Co or Ni. The temperature may be maintained at 90-140‹ F. The anodes catalyse the oxidation of hypophosphite ions to phosphite ions in the electrolyte. The carrier may be of (a) brass, bronze, A1, Al alloy, Mg, Mg alloy or (b) a non- conductive material or ferromagnetic material over either of which is deposited or laminated a non-ferromagnetic conductive material. The deposited coatings may be 10-5000 millionths of an inch thick. Their coercivities increase with increase of hypophosphite ions. Coercivities of 110 to 800 oersteds may be obtained for Co- Ni alloy deposits and 60 to 700 oersteds for Co coatings. Remanences of 15,000 to 8500 gausses are referred to. Coatings which permit a high recording density of 2000 binary bits per inch can be produced by the process.

Title: Improvements in electron discharge devices
IPC: H01J1/13
Filed: 1924-11-06
Abstract: 224,544. British Thomson-Houston Co., Ltd., (Assignees of Kingdon, K. H., and Langmuir, I.). Nov. 6, 1923, [Convention date]. Low-pressure metallic-vapour apparatus.- In a tube containing an alkali metal such as caesium or rubidium, which forms an adsorbed layer on its cathode during operation of the tube, an adsorbed film of oxygen is previously formed on the cathode so as to retain the film of alkali metal and to produce a higher electron emissivity. The tube is preferably of the type described in Specification 208,729. The, bulb is evacuated and the filament cathode is heated to a high temperature, for instance 1730‹ C. in the case of tungsten, to remove impurities and occluded gas. Oxygen is admitted to the bulb at a pressure of 20 to 30 microns and the filament heated to 1100‹ -1200‹ C. for a few seconds to form a thin layer of adsorbed oxygen. The remaining oxygen is pumped out and caesium is distilled into the bulb from a side tube containing a mixture of caesium chloride and a reducing agent such as calcium or magnesium. A part of the caesium may condense on the bulb. When the anode consists of unoxidized metal, enough oxygen is admitted to the bulb to oxidize part of the caesium, and the resulting mixture of caesium and caesium oxide removes deleterious gas such as hydrogen. Half as much hydrogen as oxygen may also be introduced to form a mixture of caesium hydrate and caesium hydroxide which removes carbon monoxide. Or the anode may consist wholly or partly of an oxidized metal; for instance, a strip of oxidized copper may be secured to the anode. In this case it is unnecessary to admit oxygen after the introduction of caesium, as the caesium combines with copper oxide to form caesium oxide. Condensation of caesium on the stem should be avoided, for instance, by heating the stem and cooling the deposit of caesium on the bulb. After sealing off the bulb the cathode is heated for a few seconds to 1030‹-1230‹ C. to remove deleterious substances from the oxygen layer. It is stated that the emission from such cathode at a temperature of 630‹ C. with the bulb at 30‹ C. is equal to that from a tungsten filament at 2200‹ C. Bombardment of the cathode by positive ions removes oxygen and should be avoided. With this object the anode and control electrode may consist of flat plates 19, 18 mounted radially on rings 23, 21, respectively, around a straight filament 17, the plates 18 being larger than the plates 19. Positive ions are formed in the spaces between the plates and are attracted to the control electrode. The electrode supports are surrounded by short tubes 10 to prevent leakage. In a two-electrode-tube a V-shaped filament is mounted in front of a rectangular anode of tungsten, nickel, or copper.
